Patent

CA 2309770

A moving-picture comparison method allowing the degree of similarity to be precisely computed is disclosed. A database stores a plurality of moving pictures and candidate feature data generated from each moving picture according to candidate timing information. After generating query feature data from a query moving picture according to query timing information, at least one of the candidate feature data and the query feature data is changed based on the query and candidate timing information so that one of the query and candidate feature data exists at a time position of the other. Thereafter, the query feature data and the candidate feature data are compared to compute the degree of similarity.
